How Does a CCTV System Work?

Closed Circuit Television, more commonly known as CCTV, is a monitoring system that provides recorded footage for security around homes and businesses.

It may be used as an additional security measure overnight or while the premises are unoccupied, or as a way for larger venues to monitor areas that cannot be seen easily.

Although CCTV includes screens and often uses coaxial cables to transmit data, it is a closed system and cannot receive mainstream television signals.

The recorded footage can be reviewed later and used as evidence if an incident has taken place, and viewed in real-time on a monitor for additional security. It is a great option for your security on the Mid North Coast.

Cameras are placed in strategic areas. In some businesses, this may be near the cash register or high foot traffic areas. Domestic clients most commonly place cameras near the front door and garage. The cameras operate as long as they remain powered, and capture activity within their field of vision.

The cameras send the footage to a central storage point, either via a coaxial cable (analogue) or via the building’s internal computer network (IP cameras). The footage may be watched real-time as it occurs on one or several screens, offering an easy overview of the entire premises.

Security footage will be saved on a DVR or computer hard drive. Systems will vary in their storage capacity, and will usually overwrite old footage when the limit is reached. The footage can also be downloaded to keep.

Newer CCTV systems can also be viewed remotely through an app or web browser with a private login, and can send notifications when unusual activity is detected.

Analogue cameras require onsite video storage and a direct cable link to the central monitoring system. These cameras do not require an internet connection, and cannot be affected by network service outages.

IP cameras use the internal computer network in a building to transmit and store their data. These cameras offer higher resolution and better image quality. The data can be transferred and stored offsite via the internet but may be affected by slow bandwidth.

Check with your local council or governing body if there are licences or requirements for installing CCTV on your property.
